Hi Panagiotis,
Thanks for quickly reply. Please see my questions below
1. On 3.5 ExecuteMarketOrder, if market is very volatile and price move very quickly, what is expected behavior of new command if no market range to bound the entry price?
2. On 3.5 ExecuteMarketRangeOrder parameters,
- what is the relationship between price base and marketRangePips?
- how should we define value of pricebase? The 3.3 does not need to submit any price.
Thanks in advance

Hi lec0456,
Can you share a cBot that reproduces this message?
Best Regards,

Hi Panagiotis,
I think I can reproduce this problem. I got the same error message "Symbol "xxxyyy" has no quote" when accessing Symbol. Here is the steps.
1. Make sure that your bot has a method call Symbol. I had tried Symbol.Code and Symbol.ToString(). Both of them give same error.
2. Use your custom workspace
3. Start your bot normally with your Live account.
4. Turn off Wifi and wait until you have "no internet connection"
5. Turn on Wifi.
6. Your bot will resume normally.
7. Stop your bot.
8. Switch to Demo account
9. Start your same bot. You will get the error "Symbol "xxxyyy" has no quote"
10. Problem will be away if you restart cTrader.
Note: the account can be Demo and then Live, or from Live to Demo. Switching from Demo to Demo can not produce error.
I can reproduce this error after your freshly upgrade in this morning.
Regards,
Noppanon

Hi Panagiotis,
Thanks for your suggestion. I think I should restate my problem.
I found cTrader has inconsitancy behavior which relates to symbol, backtest vs. live and number of decimal points in stop loss & take profit when submitting PlaceStopOrder
1. Bot will return "Invalid Request" if and only if symbol is XAUUSD, XAUEUR and take profit / stop loss has decimal points on live trade. The workaround is making sure take profit / stop loss has ZERO decimal point.
2. Bot will work fine if and only if symbol is XAUUSD, XAUEUR and take profit / stop loss has decimal points (no matter how many decimal) on back testing.
3. Bot will work fine if and only if symbol is EURUSD, GBPUSD, XAUAUD. on both backtest and live, no matter take profit / stop loss has decimal point.
So is it the known problem and pending to fix in the future?
Regards,
Noppanon

Hi Panagiotis,
It may not work to round take profit to symbol digits because
1. Symbol.Digits of XAUUSD is "2", so round to 2 decimal point, it will fail
2. On PlaceStopOrder, it takes stop loss and take profit as number of pips, not a price. While ModifyPosition takes stop loss and take profit as price.

Hi,
Now I can reproduce the problem. It relates to symbol and take profit or stop loss has decimal points with conditions.
According to the code below,
This code works with EURUSD, GBPUSD, XAUAUD. on both backtest and live, no matter take profit / stop loss has decimal point
This code works with XAUUSD, XAUEUR. on backtest no matter take profit / stop loss has decimal point .
This code does NOT work on live if symbol is XAUUSD, XAUEUR and take profit / stop loss has decimal points.
I didn't test all symbols. Just pick the symbol I trade.
